ONLINE ORDERS | QUOTATIONS | PAYMENTS
Orders and Payments
Clear answers about website orders, quotations, stock confirmation and payment processing.
You can place an order through the JC Solar Panels online shop or request a formal quotation from our sales team. For technical systems, bulk quantities or products requiring compatibility checks, a quotation is recommended before payment.
EFT is accepted for quotations and orders. The payment options currently available for online purchases are displayed at checkout. Payment methods may differ according to the order type, transaction value and payment provider availability.
Proof of payment helps us identify the transaction, but an order is released only after cleared funds have been verified in the applicable company bank account. This protects customers and JC Solar Panels against fraudulent payment confirmations.
No. Our collection points and supplier warehouses are dispatch facilities rather than public retail stores, and they do not accept cash or over-the-counter card payments. Payment must be completed through the approved method before collection is authorised.
Not always. Stock may be held at our own dispatch point or at a supplier warehouse and can change during periods of high demand. Your order is confirmed once payment and stock allocation have been processed. If an item becomes unavailable, our team will discuss a suitable alternative or the appropriate next step.
Yes. A formal quotation is useful for larger orders, complete systems, business purchases, special delivery requirements and projects that need technical design. Please provide the required products, quantities, delivery location and company details where applicable.
Only when the product page or quotation expressly states that they are included. Ordinary component prices generally exclude delivery and installation. Fully installed packages clearly identify the included scope, while any site-specific work remains subject to the quotation and assessment.
DISPATCH | SELF-COLLECTION | NATIONAL SHIPPING
Collection and Delivery
What to expect when collecting an order or arranging delivery anywhere in South Africa.
No. Warehouses are used for stockholding and dispatch and are not public walk-in retail stores. An order must first be placed, paid, processed and allocated before collection can be arranged.
Wait for written confirmation that the order is ready. The collector must have the collection reference and any identification or documentation stated in the dispatch email. Arriving without a released order reference may result in the warehouse refusing collection.
Usually yes, provided we are informed in advance and the authorised collector has the correct order reference and requested identification. For higher-value orders, additional confirmation may be required before goods are released.
Yes, national delivery can be arranged for many products through suitable third-party logistics providers. Delivery availability and pricing depend on the destination, weight, dimensions, fragility and access requirements. Ecommerce shipping is within South Africa; cross-border commercial projects are assessed separately.
Solar equipment ranges from small electronic devices to heavy batteries, long rails and fragile solar panels. A fair delivery price can only be calculated once the exact products, quantities, collection point and destination are known.
Yes, subject to prior coordination. We must confirm the collection address, packaging requirements, order dimensions, collection hours and release reference before your courier arrives. Responsibility for selecting a suitable carrier remains with the customer.
Inspect the shipment as soon as it arrives, photograph the packaging and product, note visible damage with the courier and contact us promptly. Keep all packaging and do not install a damaged component while the delivery or warranty process is being assessed.
RESIDENTIAL | COMMERCIAL | COMPLIANCE
Installations and Site Assessments
How complete installations are assessed, quoted, completed and documented.
Yes. JC Solar Panels provides complete residential and commercial solar solutions through experienced installation and engineering professionals. The service can include assessment, design, equipment supply, installation, commissioning, protection equipment, monitoring and compliance documentation according to the agreed scope.
Residential coverage depends on installer availability and travel distance, with established teams in key regions including Gauteng, the Western Cape and KwaZulu-Natal. Commercial projects can be assessed nationally. Remote locations may attract additional travel, accommodation or logistics costs.
The account provides an indication of energy consumption and tariff costs, while the load information shows the power required at any moment. Both are needed because inverter capacity, battery duration and solar production solve different parts of the energy requirement.
Not for every preliminary quotation. Photos, electricity bills, roof information and electrical details may be enough to establish a budget and proposed system. A site inspection is normally required before final design where the installation is complex, commercial, three-phase, affected by existing equipment or dependent on structural and electrical conditions.
Please provide the suburb and province, single-phase or three-phase supply, main-breaker rating if known, average electricity account, required backup loads, preferred backup duration, roof type, number of storeys, photographs and any plans for EV charging, generators or future expansion.
Where a Certificate of Compliance forms part of the quoted installation scope, it will be issued after the work has been completed, tested and found compliant. Existing defects or electrical work outside the quoted scope may need to be corrected separately before certification.
This is considered case by case. The equipment must be suitable, compatible, complete, supported in South Africa and safe to install. We cannot accept responsibility for undisclosed faults, missing components, incompatible products or warranty limitations relating to equipment supplied by another party.
SSEG requirements differ by municipality, inverter type, system capacity and connection arrangement. Registration, engineering documents or approval services are included only when specifically stated in the quotation. The design must comply with the property’s electrical supply and the requirements applicable to the project.
LOADS | BACKUP TIME | SOLAR PRODUCTION
System Design and Sizing
Understand how inverter power, battery capacity and solar-panel capacity work together.
The correct system is determined by your peak loads, daily energy consumption, required backup duration, available solar space, electrical supply and budget. A product bundle can be a useful starting point, but final sizing should be based on the property rather than only the inverter nameplate.
Kilowatts (kW) describe power: how much equipment can operate at a particular moment. Kilowatt-hours (kWh) describe energy: how much power is used or stored over time. An inverter is generally rated in kW, while a battery is generally described by usable kWh.
Backup time depends on usable battery capacity and the combined demand of the appliances operating during the outage. A 10 kWh battery will last much longer at a 500 W load than at a 5 kW load. High-consumption appliances can reduce backup duration quickly.
The number depends on the chosen panel wattage, inverter MPPT limits, string-voltage requirements, available roof area, orientation, shading and daily energy target. Panels should never be selected only by dividing inverter size by panel wattage; the complete string design must be checked.
A standard grid-tied inverter normally shuts down when the grid fails. Backup operation requires a compatible hybrid or backup system, correctly configured batteries and an approved changeover or gateway arrangement. Only the loads included in the backup design will remain powered.
It separates the circuits that must remain powered during an outage from high-demand or non-essential circuits. This helps prevent the inverter and batteries from being overloaded and allows the available stored energy to support the most important equipment for longer.
Potentially, but these loads must be identified during design. Their starting current and energy consumption can require a larger inverter, more battery storage and load-control equipment. It is often more economical to prioritise essential circuits and manage large loads intelligently.
A hybrid system can coordinate solar, batteries and the grid. An off-grid system is designed to operate without a utility supply and normally needs greater storage and generation redundancy. A grid-tied system focuses on solar self-consumption or export and may provide no backup unless specifically designed to do so.

Products and Compatibility
Practical guidance before combining solar components or expanding an existing system.
Yes, most products in our online shop can be purchased as supply-only equipment. Some specialist ranges and engineered solutions, including complete Sigenergy projects offered by JC Solar Panels, are available only as professionally designed and installed solutions.
No. Voltage range, maximum charge and discharge current, communication protocol, firmware and manufacturer approval must all be considered. A battery may appear electrically similar yet fail to communicate correctly or fall outside the inverter manufacturer’s supported combinations.
This is generally discouraged unless the relevant manufacturers expressly support the combination. Differences in chemistry, voltage behaviour, age, firmware and battery-management communication can cause imbalance, reduced performance or warranty problems.
Often yes, but expansion depends on the existing battery model, age, firmware, parallel limits and manufacturer rules. Plan future expansion before purchasing so the system architecture and battery family provide a practical upgrade path.
Possibly. The inverter’s MPPT voltage window, maximum input current, short-circuit-current limit, string configuration and total permitted PV capacity must be checked first. Roof orientation and the electrical condition of the existing installation also matter.
Provide clear model numbers and datasheets for the inverter, batteries, panels and communication equipment, together with the current wiring arrangement and intended expansion. Photographs alone may not reveal the technical limits needed for a safe recommendation.
Not automatically. Higher-wattage modules can reduce the number of panels required, but dimensions, weight, current, voltage, roof layout and inverter limits must also suit the project. The best panel is the one that fits the electrical and physical design.
Solar-geyser services are available in supported areas and are quoted according to the property, existing geyser arrangement, roof type, household demand and selected technology. An assessment may be required before a final installation price can be confirmed.
FINANCE | PPA | COMMERCIAL ENERGY
Finance and Commercial Projects
Options for qualifying complete installations, businesses and larger energy projects.
Financing may be available to approved and successfully vetted customers for qualifying complete supply-and-install projects. Approval is not guaranteed and remains subject to the finance provider’s affordability, credit, documentation and project requirements.
Generally no. Financing arranged through our project partners applies to qualifying systems supplied and installed through the approved project structure. It is not normally available for component-only purchases or installations performed independently by an unapproved third party.
PPA solutions may be considered for qualifying larger commercial SigenStor, SigenStack or other engineered projects. Suitability depends on electricity consumption, tariff structure, site tenure, financial assessment, project scale and the expected commercial value of the installation.
Commercial assessments normally require recent electricity accounts, interval or smart-meter data where available, operating hours, supply capacity, tariff details, generator information, roof or land availability, expansion plans and the organisation’s preferred funding route.
They may, when the tariff includes demand-related charges and the storage system is designed around measured load peaks. The result depends on interval data, battery power, usable energy, operating schedule, solar production and the control strategy.
Online product shipping is limited to South Africa. Selected commercial and industrial projects elsewhere in Africa may be assessed individually, subject to engineering scope, local compliance, logistics, installation partners and contractual requirements.
Yes. JC Solar Panels offers complete Sigenergy solutions ranging from SigenStor Neo and standard SigenStor to commercial SigenStack projects. These are professionally assessed and installed solutions rather than individual Sigenergy components for general resale. View our Sigenergy solutions.
WARRANTIES | RETURNS | TECHNICAL SUPPORT
Warranty, Returns and Support
How product warranties, installation workmanship and support requests are handled.
Product warranties are provided according to the applicable manufacturer or distributor terms and differ by brand and model. Warranty duration does not mean every failure is automatically covered; installation compliance, operating conditions, serial numbers, proof of purchase and inspection findings may affect a claim.
Qualifying installation work completed under an official JC Solar Panels quotation and invoice carries the workmanship warranty stated in our terms and conditions. It covers verified defects caused by the original installation workmanship, not every future product failure or external electrical event.
No. A manufacturer warranty relates to the product and its specified defects. An installation workmanship warranty relates to the manner in which the quoted installation work was performed. A technical inspection may be needed to establish whether a fault comes from equipment, installation, settings, the grid or another external cause.
Complete the online warranty claim form and provide the invoice, product model, serial number, installer details, Certificate of Compliance where required, fault description, error codes, photographs and any supporting test information.
Not automatically. The product may first require inspection, testing, manufacturer authorisation or return to the distributor. The outcome may be repair, replacement, credit or rejection according to the cause of failure and the applicable warranty terms.
Return eligibility depends on the product, condition, packaging, timing, whether it was specially ordered or customised, and applicable consumer law. Contact us for authorisation before sending or delivering any item. Installed, damaged, altered or incomplete products may not qualify as ordinary returns.
Not necessarily. Manufacturer warranties generally cover eligible equipment rather than every call-out, travel cost, diagnostic service or labour charge. If inspection confirms a valid JC Solar Panels workmanship defect, the matter will be handled according to the installation warranty terms.
Yes. Unauthorised changes to wiring, protection equipment, batteries, communication, firmware, inverter settings or system configuration can affect product and workmanship warranty coverage where the change causes or contributes to the fault. Contact us before another party modifies the installation.
